Biology Question on recombinant technology
Process used for amplification or multiplication of DNA for finger printing is
A
Polymerase chain reaction
B
Nesslerisation
C
Southern blotting
D
Northern blotting
Answer
Polymerase chain reaction
Explanation
Solution
Polymerase Chain Reaction (PCR) technique is a method for making copies of specific stretches of DNA from single cell as well as from DNA libraries. Thus, PCR has allowed the analysis of minute quantities of evidences and has facilitated DNA finger printing.
